CHARLES MORRILL, OF NEWV YORK, N. Y.

SAW-SET.

SPECIFICATION forming part of Letters Patent No. 468,816, dated February16, 1892.

Application filed July 31, 1891. $eria1 No. 101.325- (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES MORRILL, a citizen of the United States, anda resident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Saw-Sets, of whichthe following is a specification.

My invention relates to improvements in saw-sets provided with asuitable housing for the protection of the actuating-spring surroundingthe horizontally-moving hammer.

The invention also relates to an adjustable guard, all of which will befully described and shown hereinafter.

lleretofore the actuating-spring and hammer of saw-sets have beenexposed, thus enabling the dust and refuse to settle between the'convolutions of the spring and in time clog the same to such an extentas'to cause it to become inoperative. They were also provided with aguard having a broad vertical slot adapted to accommodate acorrespondingly-shaped hammer, the latter of which, when operating upona-narrow saw, would cause it to buckle, thereby giving the blade of thesaw a curved shape after having its teeth set. I propose to obviatethese objections by my present invention, which will be fully pointedout in the claims.

My invention consists in providing a suitable inolosure for thereception of the actuating-spring surrounding and connected with thehorizontally-moving hammer.

It also consists of an adjustable guard so arranged as to enable theoperator to set the teeth of narrow saws as well as broader ones.

It further consists of the arrangement of the heel of theoperating-handle and the end of the horizontally-moving hammer.

In the accompanying drawings, Figure 1 represents a plan view of thedevice having the adjustable guard removed. Fig. 2 represents alongitudinal vertical section of the device, in which is shown theprincipal features of my invention. Fig. 3 is a transverse section ofthe housing, taken on the lineX X of Fig. 2; Fig. 4 is a detail view ofthe hammer detached. Fig. 5 is a face view of the adjustable guarddetached.

Similar letters refer to similar parts throughout the drawings, inwhicha represents the housing, forming a part of the main body of thedevice, and b is the depending lug, having an internal screw-threadedperforation whose longitudinal center is arranged on a suitable angle tothe horizontal center of the main body of the device. The screw-threadedperforation aforesaid is adapted to receive a regulating-screw c, theforward end of which is swiveled to the adjustable guard d by means ofthe set-screw d, which latter also regulates the friction of the screw0. The guard is provided with the vertical narrow slot e, through thelatter of which the narrow end of the hammerf passes when in operation.The rear end of the hammer aforesaid is provided with a semicircularbead g, arranged transversely to the longitudinal center thereof. Thebase of the bead g terminates in shoulders h h, the former of whichengages normally with the corresponding shoulder 2', forming a part ofthe heel 7c of the operating-handle 0, the latter of which is pro-.vided with the nose Z, which rests normally upon the upper surface ofthe housing, thereby regulating the movement of the hammer learwardly.

It will be observed that the convex portion of the head 9 aforesaidengages with a corresponding concavity made in the heel 7c of theoperating-handle 0.

It will be obvious that the teeth of narrow saws can be operated uponwhen shifting the guard (1 forward, as shownin Fig. 2; butwhen broadersaws are to be operated upon the guard may be shifted rearwardly, asshown by the dotted lines in Fig. 2. It will also be obvious that thehousing surrounding the actuating-spring will prevent the refuse whichusually accumulates in workshops from clogging the spring, which isoften the case in saw-sets having their actuating-springs exposed. Itwill also be obvious that the narrowness of. the end of the hammer andthat of the slot of the guard will enable the operator to set the teethof narrow saws without distorting their straight alignment.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a saw-set, the combination of thehousing forming apart of the main body of the saw-set, theactuating-spring completely covered thereby, and a horizontal1y-movinghamlner connected with said spring, substantially as shown anddescribed.

2. In a saw-set, the combination consisting of the adjustable guardhaving the narrow Vertical slot therein, said guard being swiveled uponthe forward end of the adjustable screw, and the set-screw adapted tohold the guard and adjusting-screw together and to regulate the frictionof said adjusting-screw within the guard aforesaid, substantially asshown and described.

3. In a saw-set, the combination consisting of a horizontally-movinghammer having its forward end flattened and a semicircular bead arrangedtransversely on its rearward end, 15

said bead terminating in shoulders adapted to engage with correspondingmeans connected with the operating-handle, substantially as shown anddescribed.

Signed at New York, in the county of New 20 York and State of New York,this 20th day of July, A. D. 1891.
